MUSIC-SHEET TURNER.

Specification of Letters Patent.

Application filed April 15, 1916. Serial No. 91,315.

To all whom it may concern:

Be it known that we, Conxnmos XV. SMITH and Eowann A. OBnmx, both citizens of the United States, and residents, respectively, of the city of New York, borough of Manhattan, in the county and State of New York, and of the city of New York, borough of the Bronx, in the county of Bronx and State of New York, have invented a new and Improved Music-Sheet Turner, of which the following is a full, clear and exact description.

Among the principal objects which the present invention has in view are: to provide means automatic in character for turn ing a sheet of music; to provide a folder for carrying sheet music, which may be used as a rack for holding sheet music in service.

Description.

The preferred embodiment of the invention as shown in Fig. 1 of the drawings, comprises two folding side covers 11 and 12. These covers are preferably constructed of binders board, and are operatively united by hinge butt 13, the hinge pin for which is a rod 1 1, which rod extends between the hinges as well as through the knuckles thereof.

The rod 14 has a laterally extended arm 15, the free end whereof is turned to form a hook 16 notched to receive a spring latch 17 The latch 17 operates to hold the extension parallel with the cover 12 and in juxtaposed relation thereto. The arm 15 is normally thrown against and upon the cover 11 by the operation of a coil spring 18 which is wrapped on the rod 14.

The latch 17, as shown best in Fig. 1 of the drawings, comprises a wire bent upon itself to form a coil 19, and to receive an anchoring pin 20, to engage a stop pin 21. The pin 21 is employed in part to hold a small hollow turret 22, through an eyelet in the center whereof the hook 16 enters. The latch 17 passes through slots 23 formed in the sides of the turret 22. The free end of said latch is an eyelet 24 to receive a pull cord by which the latch is operated to release the hook 16 to permit the spring 18 to rotate the rod lt and lay the arm 15 upon the cover 11.

The pull cord 25 has at the end, a pendant 26, by means of which the operator may rapidly and easily engage said cord. To move the cord in a path parallel with the cover 11 and to prevent the entangling of the same with the parts of the apparatus, a guide wire 27 is provided. This wire has a pivot 28 and an eyelet 29. The eyelet 29 holds the cord 25, which, in service, is secured thereto, said cord below the wire 27 tending to rock the said wire on the pivot 28 and not to slide through the said eyelet.

The purpose in rotating the rod 14 and extension 15, is to turn the intermediate sheet 30 of the music. The other sheets, 31 and 32, of the music remain in spread position on the covers 11 and 12.

To assist in turning the sheet 30, the extension 15 has a spring-actuated clamp plate 33. The plate 33 is pivotally mounted on the extension 15, and is normally held by a spring 34; clamped upon the loop 35. Extending from the loop 35 is a rest bar 36, for partially supporting the intermediate sheet 30.

In Figs. 5 and 6 of the drawings, a modified form of the invention is shown. The modification consists primarily in uniting the covers 11 and 12, by a flexible bookbinders hinge 37. When employing an apparatus constructed and arranged in accordance with the modification, a number of pieces of sheet music may be carried beside that arranged for manipulation by means of the turning apparatus.

Operation.

W hen employing an apparatus constructed and arranged in accordance with the present invention, the music sheets are Patented J 11110 26, 1917.

placed between the covers 11 and 12, by first lifting the coil 19 of the latch 17, to placethereunder the last sheet 32. The clamp plate 33 is then forced to open from the loop 35, to the position shown in Fig. i of the drawings. The intermediate sheet 30 is then placed on the loop 35 and the extension bar 36 thereof. The plate 33 being released the spring 34 thereof operates to force the same to grip the sheet 30.

If the arm 15 has not been previously locked by the latch 17, this is now accomplished by depressing the hook 16 thereof into the turret 22 until said latch 17 engages the nick or recess provided in the side of the hook for this purpose. The latch therefore operates to hold the arm 15 in position.

The covers 11 and 12 are now spread and placed upright on a music rack, with the pendant 26 of the cord 25 hanging in position convenient to the hand of the musician. hen it is desired to turn the intermedi ate sheet 30, all that is required of the musician is to engage the pendant 26 and draw the same down to rock the wire on its pivot 28 and draw the latch 17 out of engagement with the hook 16, the hook 16 be ing'thus free the spring 18 is sufficiently strong to rotate the rod 14 and the arm 15 to lay the same together with the sheet 30 upon the cover 11.

0 Zaim.

A music sheet turner comprising stiif covers hingedly connected to open bookwise; a pivotally mounted rod having a lateral arm disposed between said covers; a spring operating to normally hold said extension in juxtaposed relation to the left-hand cover when the covers are opened; means for holdi'ng said extension in juxtaposed relation to said right-hand cover, said means embodying a bent wire latch shaped to form a coiled extension overlying the sheet below that to be turned, for preventing the lifting thereof when the intermediate sheet is turned; and means mounted on said arm for engaging a loose sheet, said means embodymg a spring-actuated clamp mounted on said arm.
